Function Documentation

template<typename Execution , typename... InputIterators, typename Identity , typename Transformer , typename Combiner , requires_iterators< InputIterators... > = 0>

auto grppi::map_reduce	(	const Execution &	ex,
		std::tuple< InputIterators... >	firsts,
		std::size_t	size,
		Identity &&	identity,
		Transformer &&	transform_op,
		Combiner &&	combine_op
	)
